An integrated amplifier is a device that combines two essential audio components: a preamplifier and a power amplifier. The preamplifier boosts low-level audio signals from sources like CD players or turntables, while the power amplifier drives the speakers, producing sound. This all-in-one design simplifies audio setups, reducing the need for multiple separate components. Integrated amplifiers often include additional features such as built-in digital-to-analog converters (DACs) and various input options, making them versatile for different audio sources. They are popular among music enthusiasts for their convenience and ability to deliver high-quality sound in a compact form.
